BY @mgm ATTORNEY Patented Dec. 9, 1930 'UNITED STATESA BAH CENTOFANTI ANNIBALE MARCHETTI, OF YOUNGSTOWN, OHIO RADIATOR CAI AND MOVABLEHEADLIGHT Application filed April 20,

This invention relates to improvements in movable lights adapted yforuse' upon motor vehicles and the like." j

.An object of the vinvention `contemplates supporting arms for theklights having swivel connection therewith. n

Another object of the invention comprises rod members operativelyconnecting the connections lof the lamp with the supporting arms to tiltand shift the lights to occupy ldesired ositionsf An a ditional objectof the invention con-k sists inthe provision of an operating memberAcommon to both the tilting and shifting i5 rods whereby both motionsmaybesimultaneously imparted to the lights.

With the aboveand other objects in view, the invention further consistsof the following novel vfeatures and details of construction,to vbehereinafter more fully described, illustrated in the accompanyindrawings and pointed lout' in the appende claims.

In the drawings y p e Figure 1 is a front elevation of a motor vehicleequipped with the present `form of 1i ht Y Y ure 2 is a sectional viewVtaken through a ra iatorcap and illustrating Vthe connection of tliearms and relativearrangement of the rod members. j v Figure 3 isalongitudinal sectional view taken onv line 3'3 of Figure 2.

' Referring to the drawings in detail, where- 4 in like characters ofreference denote corref5 spending parts, the reference character 10 maalsem; no. 356,780.

indicates the body portion of a radiator cap adapted for threadedconnection with a radiator neck 11 substantially as illustrated inFigure 2 of the drawings. A closure cap 12, carrying an ornament 13 ofany suitable 50 design, is hingedly mounted, as at 14, to the upperperiphery or mouth of the body portion of: the cap.` Supporting armsv15V of hollow formation, are extended laterally in `oppositelydisposed" relation upon diametrically opposite sides of and havingcommunication Vwith the interior or bore of the radiator ca body asillustrated in the'aforementioned re. .Y

A sh'aft'16,passed through the arms and body ofthe radiator cap, isbearingly mount'- ed adjacent its ends for rocking movement within'apertured bracket armsV 17 carried upon the inner side walls of thesupporting arms 15. Yoke members 18, carried upon 6,- the extremities ofthe shaft 16, are adapted to accommodate the balls 19 formed upon theinnermost ends of extensions 20 carried upon the innermost ends of lampAcasings 21, said yokes being adapted for pivotal connection with theballs19,l Thel extensions project through the' openings 22`in theforward side walls ofthe supporting arms 15 as manifestfrom theillustration ofour invention in vFigure 3 of the drawin s.A Bars 23 and24 respectively, mounted or oscil latory movement within ears 25 locatedupon the inner side walls of the supporting arms 15, terminate toprovidera'ck teeth`26 upon the adjacent faces of the innermost Vendsthereof.

The bar 24 is provided with an L-shaped innermost end27 whereby `theteeth thereon may be disposed inspaced. relation and in parallelism withthe teeth upon the companion end of the bar 23 to effectivelyaccommodate a gear member 28 therebetween. -Retaining plates 29 carriedupon the opposed sides of the gear'28 and having the ,peripheriesthereof extending for appreciable distances beyond the circumference ofthe gear, are adapted to align the toothed ends of the bars 23 and 24for meshing engagement with the gear.

Segments 30, of arcuate shape, are provided upon the innermost ends ofthe balls 19 and which are adapted for engagement with square threads 31embossed upon the outer side walls or surfaces of the bars 23 and 24upon the outermost projecting ends thereof.

An operating rod 32, common to both the shaft 16 and bars 23 and 24, isextended and projected through the body portion of the radiator cap, thegear 28 being: fitted upon a squared portion 33 adjacent the ,outermostend of the operating rod.- Square threads 34, horizontally andcircumferentially disposed in spaced relation upon the forwardend of theoperating rod 32, areadapted for meshing engagement with the gear member435, preferably located and keyed or otherwise fixed at an intermediatepoint in the lengt-h of the shaft 16. i

The innermost end of the operating rod 32 is formed with a multiplicityof circumferentially arranged ribbed portions between which a springpressed finger 37 is adapted for selective recept-ion after theoperating rod is extended and retracted through a hori- Zontallydisposed opening in the instrument panel 38l for a motor vehicle,substantially as illustrated in Figure 4 of our drawings. A handlemember 39, included upon the innermost end of the operating rod 32, islocated within convenient reach of the motor vehicle driver. A pointerhand 40, carried by the handle 39, is adaptedto be shifted across theface of a dial 41 whereby ,the angularity of the lights 21 with respectto the vehicle may be readily apprehended.;

From the foregoing ydescriptionand accompanying drawings it is obviouslyapparent that shifting movement of the operating rod 32 will cause thelights 21 to be shifted or tilted upwardly and downwardly whereasrotation of the opera-ting rod in either direction willcause thelightsto be oscillated across the roadway to narrow or widen the beam oflightthrown in advance thereof.

In Figure 7 of ourdrawings, we have illustrated a modified form of gearmember, such as indicated at 42, and whichwmay be employed in place ofthe gear member 23. The gear member 42 is not provided with retainingplates 29 but the teeth therefor are sunk within a channeled raceway 43in the outer periphery thereof. Bars 44.y and 45 operable by said gearare therefore provided with tooth portions adapted to be projectedwithin the channeled raceway 43 for meshing engagement with' the teethVtherein. This construction is optional ,to that as disclosed in `Figure8 of our drawings.

The invention is susceptible of various menate changes in its form,proportions and minor details of construction, and the right is hereinreserved to make such changes as properly fall within the scope of theappended claims.

Having thus described the invention, whatl is claimed is 1. A movableheadlight construction comprising laterally disposed arms havingcommunication with the interior thereof, lamps F for the arms havingswivelconnection therewith, shaft establishing connection between themountings for the lamps, segments carried by said mountings, bars havingtooth portions upon the ends thereof adapted for engagement with thesegments, an operating rod, and gear inembers'carried upon the shaft andoperatingrodto provide a common control: means whereby the lamps may becollectively and simultaneously ytilted and laterallyfsliiftedreispec'tiv'e'ly.y l x 2.
